ReadytoSky F405 FPV Stack with 16 MB Blackbox, 60 A 4-in-1 ESC and 2.5 W 5.8 GHz VTX
The ReadytoSky F405 FPV Stack combines a high-performance F405 flight controller, 60 A 4-in-1 brushless ESC, and Ultra2500 FPV video transmitter into a complete electronics platform for racing, freestyle, and long-range multirotor builds. The flight controller uses an STM32F405RGT6 processor running at 168 MHz and includes Betaflight SPI OSD, 16 MB integrated Blackbox flash memory, 6 UARTs and onboard voltage sensing. Support for 3-6S LiPo batteries and dual 5 V / 12 V BEC outputs simplifies integration with receivers, cameras, GPS modules, and digital or analogue FPV equipment.
The 60 A 4-in-1 ESC operates from 3-6S power and uses BLHeli-S firmware with support for DShot600, DShot300, DShot150, OneShot125, Multishot, and PWM motor-control signals. The included Ultra2500 VTX operates across the 4.9-5.8 GHz range, provides selectable output levels up to 2500 mW, and supports 64 channels, IRC Tramp control, and PAL / NTSC video. Together, the stack provides flight control, high-current motor drive and high-power FPV video transmission in a standard 30.5 x 30.5 mm mounting format.
